Of the 3 bullets tested, this bullet is hands down the one my rifle prefers for accuracy. In my load development, it produced several groups under .5", including two at around .3". So from an accuracy standpoint, this load was the favorite going into the test, but I wanted to get an idea how it would perform.

Load data: 129gr Hornady SST, 38.5gr Varget, Sig brass, Fed. 210M primer, 2791 fps
